Graphic design in the 20th century was used as propaganda during World War I. It was used to make the enemy look bad throughout the war and they also used graphic design to try to get people to sign up for the military. James Montgomery Flagg, American illustrator, created the “I Want You” poster that featured Uncle Sam and was widely known throughout WWI. A major contribution to the field of graphic design was that this art movement brought on the use of posters and propaganda.
